Bella,

I worked in the running shoe industry for a few years and was the technical / biomechanical person at a running specific store.

Shin splints can be caused be a couple of different things but the most common is the pronation, or way that the foot rotates from heal to toe, rate of the foot. If you foot does not follow the typical path it will put added strain on different muscles / bones of the body from the foot to the lower back. This can be corrected (to an extent) by wearing the proper shoes. I can't actually diagnois this from here without watching you and preferably looking at some of your older running shoes.

The Asics GT-2110 is indeed a great shoe. However it is built for an over-pronator, that is someone whose foot tends to roll inwardly more than the ideal motion. Over-pronation is very common amongst runners and therefore over-pronators shoes tend to dominate the market. However, knowing your body type you are just as likely to be under-pronating, rolling more towards the outside, as you are over-pronating. I say this because in my experience many of the smaller bodied females tend to under-pronate (some people will call this supinating). Not to mention that shin splints are a very common problem with people that under-pronate (because of the way it strains the muscles) but you can get it from either type of pronation. It will just change where it is you feel the pain, because it is pulling in different areas. I can definitely understand your pain because I struggle with shin splints myself (because I under-pronate).

Has the pain gotten worse since you got your new shoes? If so that would also lend me to think that you under-pronate because the GT-2110 would have been trying to force your foot to roll more towards the outside (which would be good for an over-pronator) only making the problem worse if you do under-pronate.

Ok now that I have rattled all that off I would highly recommend that you go take your butt to a running specific store and carry a pair of your older, worn down running shoes with you so that they can look at the tread wear. They should also at least watch you take a few strides and some of the high end stores will even video-analysis your stride (overkill and unnecessary in my opinion). Of course if you want a quick and easy solution take a couple pictures of the soles of your old running shoes and post them here and I will try to analyze them myself. I can even help tell you what shoes you want to look for if you need advice there too.
